PWA 23 para 14 has a statement that, paraphrased says , “take days off in the current bid period or a future bid period by agreement with crew scheduling”

2 questions

I know you can move the PB days via PCS as you would x-days....but is there a time/method to get them placed somewhere other than at the end of your current X-day block as you agree to fly a GS?

Can / will crew scheduling just move PBs into your bank as PDs if you ask them?
