Its getting kind of tiring to have to remember every objective, bounty, and seasonal challenge that can be done together. Is there a tool that helps figure this out for you? Ex: if doing strikes as arc and getting arc machine gun kills would fulfil multiple challenges.
#Is there an objective tracker that helps you be more efficient?

I don't know if there's something for efficiency like you've described, but I do know the Destiny Recipes website tracks what bounties you have and are available, which can help for bounty prepping xp for new seasons.

Download DIM (Destiny items manager), In the progress tab you can group seasonal by weapon types and activity types.
(Can also use dim in browser)
