FIlter Queue on Formula Checkboxes

Is there any way to filter on formula-based checkboxes in a queue? We have 7 checkbox formulas that are either true or false based on inputs entered throughout a project lifecycle and they correspond to different internal workflows that need to be cleared before the project can move to the next level… I would love to use a picklist to filter on the workflows but a project could potentially fall into two or more workflows at the same time so we need to be able to mark them (and search for them)  as such.
