Pause Guiding while using FlipFlat

Hi, I am having some issues with Guiding with Phd because I use an OAG and a FlipFlat for my flats. I would like to be able to pause or stop guiding while taking flats. Right now Phd looses the guide star due to the flipflat closure and then fails. Sometimes causing the whole guiding process to fail, even when going back to taking lights, after the flats finish.
Is it possible to add Pause Guiding while taking Flats to the guiding tab?
