Question: ListTools "Exclude" function

Hello, i need to remove specific elements of a list but cannot do so with the conversion to a set and the use of the difference operation, because there are other repeatitions that are important so i cannot impose the condition of uniqueness in the process of excluding these elements, and want to keep other repeatitions in the original multiset.

I know this must be fairly straight forward because the "Remove Duplication" function retains the order of the original multiset

EDIT: i seem to have found a way to it using the "SearchAll" function from the ListTools package, so i can then reconstruct a second list by specifying a set of sequence ranges paritioned accordingly to the indices of the elements of the original i want removed that are obtains using this "SearchAll" function
