How to use surface lithology (outcrops) to constrain surfaces

Hello, i'm new to leapfrog and I need some expert help.

I'm working on a model consisting of basement (TCS+TPG) and Quaternary deposits (ac+af+gi). I'm working only with a geological map (no borehole at the moment). Below you can see the model with basement in brown and gi (glacial deposits) in turquoise. gi is modeled as Erosion (in contact with both TCS and TPG) using polylines with polarity.

The model predicts gi (several m thick) on the mountain slope where i know i have mainly the basement (below the draped geolgical map).

How can I use the outcrop to assign volume to TCS? I would like that the gi is present only on the left part of the model and not along the slope.

Thank you
