HCM Groups that combine assignments

Summary

Is it possible to look at employees who meet conditions in both assignments

Content

Hi All, 

I have a groups of employees who can claim different Time Types depending on the Job they are doing, currently they are in separate HCM Groups  but a small group have multi assignments where they should be able to claim either. My idea was to create a HCM Group that includes multi assignments and looks at both jobs with an AND clause. 

I think this is logical because it is looking at the assignments for inclusion. Does anyone have a work around for this?
