Hi Javier,
Yes you can map for a radio selection popup. Here is how you can change your script to allow the user to pick.
You will notice that the cursor position needs to be on the correct line based on the option selected by the user.

I have to warn you though (I don't have access to test this tcode in my environment) but I know based on experience with other condition setup (Pricing conditions for example), SAP will often have different subscreens and sequence based on user's selection of the specific key combination. So ideally, you want to record both scripts individually first, one for each key combo. Then you can consolidate both into one (just copy and paste) and create IF conditions around each one. At runtime, it would only execute one of them based on the IF condition being true, driven by the user's selection of the Key combo.
Hopefully that makes sense.
