Hypothetical:
Lets say I have Khan uploaded in my CW formation.

If I improve Khan with sancts or stars

Will the Khan in my CW formation reflect these improvements?
Or do I have to upload the formation again to reflect the changes?
Or do I have to pull Khan out of the CW formation then put him back in, then upload again, to reflect the improvements.

Also, if I remove Khan's gear and runes

Will the Khan in my CW formation lose his gear and runes?
Can I move Khan around in my CW formation without him losing his gear and runes?

Does each time I hit the upload button, for my CW formation, reset all my heroes to their current status/gear/runes or only those that I have moved or substituted?
