periodic mass copy

Hello everyone, I need your help for theses issues:

1- periodic mass copy : if the date placed in service for an asset is different between corp book and tax book, will the cost adjustments be copied in tax book or not?

2- the current period in tax book is Dec-17, but for the corp book is Oct-19: I have tested periodic mass copy in Dec-17 but I noticed that the program copy all adjustments from Dec-17 to Oct-19; is there a way to copy only the adjustment of dec-17?

3- customer has performed an initial mass copy on 26-Nov-17, then close the period. now we want to launch periodic mass copy on dec-17, can he bring the adjustments from 26-nov-17 to 30-Nov-17 also? if he doesn't, how to copy the adjustments during this days?
