Selecting multiple blocks in Drive Map

Hello!

I'm talking about the new beta with drive map.

I'd like to see if I could select more then one block highlight in drive map, for instance with the CTRL key I could select Fragmented and Fragmented (low seizure) to highlight.

While I'm defragmenting I usally highlight yellow (reading) and green (writing) block, however, I'd like to highlight them together.

Thank your for in advance.

(P.S Defraggler is awesome!)
