PF2e Untrained Improvisation Question: How to add level-based variable to rolls?

So a player of mine just took Untrained Improvisation. They are currently just adding their level [under the temp column] in every untrained skill they have and will have to update it every level. I don't like that.

Is there a way to add @{level} somehow? I'm thinking to add it in the notes, but just "+@{level} Thanks to Untrained Improvisation"  means they have to do mental maths and they said no to that. Is there a way I can reference the roll that was made through the character sheet in the notes? Like "@{level} + [die roll] = [RESULT] Thanks to Untrained Improvisation"?

Hi FuriousAngle, sorry your post got ignored for so long (I only just saw it myself). In case you haven't found the answer already, there's a sheet setting in Options under Skills, as shown in the screenshot below:

You can set Untrained Proficiency to Half-Level when a character has that feat and they're below 7th level, then set it to Level when they reach 7th.

Hi Persephone! Thanks for the reply! I definitely appreciate it. 

I hadn't found an answer, so I think yours might work perfectly. Thanks again!
