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 in a way that those sales orders are considered for future SPL check. Not sure if this is supported. I need this for testing a scenario.

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
