Buff uptime combat only?

Hi all! I was wondering if you can filter buff uptime to only include uptime during combat in a dungeon log. Both walking between mobs (especially when carried by angels etc), and having it linger after killing mobs skew the uptime%. As far as I can tell, logging does not discriminate.

I am looking to see how much the paladin legendary Of Dusk and Dawn actually affects my throughput.
