Workflow rule condition in case module

I can set criteria to include Accounts by Tag when creating a workflow rule using the Accounts module. But I'm looking to do the same thing when setting criteria on the Cases module. It allows me to select the Account as a field option but the only criteria are contains, doesn't contain, is, isn't etc...

Just wondering if there is a workaround or if this can be implemented. Currently, I need to manually add every account that has the specific tag I would like to apply the workflow rule.

Thanks
