Blockout's on appointment guide

We currently use appointment guides for report of findings and new patients. However we block out quarter past and quarter to the hour to allow 6 patients per hour. If no ROF or NP is booked in we allow our CA's to book standard adjustments in here. At the moment if you add a blockout on an appointment guide the blockout goes to the back and isn't a clear blockout like the rest. I feel it would be beneficial if the blockout's were applied on top rather than behind an appointment guide.
