Mass un-blocking of sales orders and uploading positive list

Hi Experts,

I have few queries and need your expert help on this. Please pardon me if this looks like very basic questions.

1) Is there a way to un-block sales orders in mass in GTS.

2) Can we upload the positive list for multiple BPs at once rather then manually moving them to positive list one by one.

Any help would be really appreciated.

Rgds
