Parameter Feature

Hi Everyone,

I want to do a pretty easy stuff, but I can't find any solution:

I'd like to have in the part history a parameter, as a feature.
As a empty/dummy feature that has 1 or more parameters. Ideally I would like to have numbers and string, but I suppose could be possible just with numbers.

The reason is to maintain a logic sense of where the parameter is required, not going inside the "user expressions" every time, that's very chaotic.

Another similar idea is to assign parameter to a feature folder...

Do you have any suggestion about this topic?
Realise dummy feature (as a move feature) just to use its parameter seems not a very clean way...

Thanks!
