GPI - How can I filter assignment extra information with the usage of assignment start date

Summary:

We are creating a GPI where we need the info that is stored in the additional assignment info segment. We can add it to the extract definition, but we need a fitler that it only shows the valid section for the assignment start date and not all section. However I don't find a way to include assignment startdate into the filter. I cant add it to connected data groups as there will be assignment start dates where the additional assignment info will not change, so won't ahve a new startdate.
