Conditional formatting help please!!! For the life of me I cannot figure out how to highlight multiple vertical cells but not the whole column when a condition is met. Any help is super appreciated!

To clarify, I have a repeating table in range A2:G400. What I need to accomplish is highlighting A2:G4 when F2 = "Blah", and again highlight A5:G7 when F5 = "Blah", but using a single conditional format to do so for whole table range within A2:G400.
