A: Yes I do

and personally, I prefer "Withdraw" and "Start staking", but yes you can do that, just be careful, because sending CLO to the Cold Staking during a round would reset your counter to zero.
I will than wait to reach again my 100% stake period and first "Withdraw" the whole amount and re-stake it again, cause if you take out only the staking reward you cannot "Withdraw" the rest (at least I got this issue)
