AHK Branching KeyWaits in Middle of Hotkey

Question

I work in a doctors office doing billing. The programs made for this job are very basic and are absolutely riddled with bugs, so I repeat parts of my code a lot to make certain they work. I used two programs, one for the billing side, one for the chart. Right now, my hotkey grabs the date of birth and Medical Record Number of the patient from the billing side, goes to the chart side, searches for the patient based on those two things (normally the MRN would be sufficient, but Epic blows, so it's not enough) selects the patient, clicks "Chart Review," then waits for me to select a service date. Upon left click, it tabs back into the billing side so I can copy information to it. the issue is, sometimes the patient did not show up, and I have to record this. If they didn't show, there's no chart to click, and I have to click somewhere else to double check that they didn't show. I need a branching type of keywait where if I click, it tabs into the billing side, or if I hit A or something, it clicks appointments, and past, then tabs back to billing and clicks "Typed Notes". I can manage everything besides the branching part. Getkeystate statements don't seem to work, and I can't use an if statement with keywaits (apparently).

The commented part was my last attempt, but I've been googling to find a real idea to try for a while. Any help is appreciated!

Edit: Maybe a "if I click here do this, or if I click here do this" kind of statement will work. I can get the dimensions of the Chart Review window vs the toolbar button for appointments. I've been experimenting with this for another task, but it might work here. Help with that would be appreciated too!

Edit: @Bob, Actually, and sorry for the late reply, I found that looping a small statement with a few keywaits of very short lengths works well for me. I'll paste my code below. And this is just a snippet, so it's not the full code.

    }
    KeyWait, Escape, D, T0.02
    If !ErrorLevel
        Return
    KeyWait, ., D, T0.02 ;They do not appear to have shown up for their appointment, so check the appointment tab

I can't use an if statement with keywaits

There is a way to "abuse" Input command with L1 and V (might be good idea to throw in I as well) options to act as (somewhat limited) KeyWait replacement. That should work for your usage case.

(...)
Input,var,L1IV ; will act as KeyWait
if (var="a") {
    foo:=Round(Sqrt(1764))
    TrayTip,,The number is %foo%
}
else if (var="s")
  MsgBox Sssnaaakess 
(...)
