Is it possible to customize responsibilities form Menu

Dear Colleagues,

I have 10 different legal entities already setup into our system

every legal entity includes around 5 responsibilities (AP,AR,GL,CE,EXP...)

Around 50 responsibilities are attached to one user

when the user login to the system and open forms ==> around 50 responsibilities appear in one list

==>issue: the end user is complaining about the long list

Question:

what is the best practice to make these responsibilities lisible and group by legal entity?

is it possible to customize the responsibilities form: means at the first login the user have to select the appropriate legal entity and by selecting one another sub-responsibility form appear including all responsibilities belong to that LE?
