Avoid duplicate attempts caused by the collision of different masks

[JustAHash]

Say for example i try the following mask made up of lower case and numbers -1 ?d?l  ?1?1?1?1?1?1?1?1?1?1 without much success.
Upon figuring out the above mask doesn't work I then create my own custom charset by removing several lower case characters and adding other upper case characters from the above already tried charset.

How can i try my newly configured mask without computing twice the collision/intersection of the two masks?

Is there some tool that could generate a list of masks which represent the difference between the two or something simillar?

Can i apply a conditional rule to exclude attempts of the form " -1 ?d?l  ?1?1?1?1?1?1?1?1?1?1" using hashcat or some other tool?

Couldn't find anything so far, is it possible what i'm trying to achieve?
