Filter lookup based on 2 sources (Account, Partner(Also Account))

Hello everyone,

I have a contact lookup in service section that i want to filter it where Contact.Account = Service.Account, also there is a lookup in Accounts section called "Partner" , which is Also a "Account" lookup . 

i want to filter the contact field that retrieve the contacts that belong to this partner, in addition to the contacts that belong to the sub-account ( the one that has been chosen in the service.

 is there a way to make that happen? (i tried to add 2 filters in business rule but didn't work. 

thanks in advance.
