Select from configured list with equation in assembly

Is it possible to select a configuration from a list via an equation in an assembly?

I need the size of trim cap for channel letters to be based on the height of the channel letter. When the letter is 18" tall or less 3/4" is used, 1" if taller than 18". I'm using the Beam FS to create the trim cap around a profile in a part studio. Then I create a subassembly of the trim cap so it is all grouped together when put in the final assembly. I would like to have the size of the trim cap automatically selected based on the height of the letters. Currently I have created a list selection where I'll have to remember to choose the right size based on the height selected.
I'm wondering if I need to use a sketch native to the part studio to accomplish this or if I'm just missing something.
I can't share my document because the customer doesn't want their IP to be public.

    I think the way I would do this is to have just a length configuration in the part studio (rather than a list), and then in the assembly, use some kind of ternary statement as the input to the part studio config:

    (#textHeight > (18 in)) ? (1 in) : (0.75 * in)

    I can mock up an example if this doesn't make sense.
    So I need to change the list in the trim cap profile part studio to a variable? I was trying to avoid this because there are really only 2 possible configurations, but not a big deal I guess.

    @Cris_Bowers this may be closer to what you want, combining variables, lists and arrays: https://cad.onshape.com/documents/36d5314a70153cbd63de384f/w/ecc6d196a635c11c03cad1c8/e/880b4fac43003796ddcb1b97

    The use case is only true for this particular customer. Another customer might want 3/4" for all letter heights or require the change to 1" at a different height. I don't really want to make a different trim cap profile specific to customers and it doesn't make sense to add an additional configuration table for customers because we might only make a single sign for a customer and never deal with them again.
