Block Multiple Items

We recently completed an inventory and realized how many unused items we have built in the system. I would like to block a large amount of them, but do not want to scroll through each item card and check the blocked square. Is there a way to do it in a more efficient way?

Thank you.

You can have your partner build a dataport for you to import a list of items and block them.

or just use simple Excel Mapping Tool. make one with table 27, Item.
use field only (A) “No.” and (B) “Blocked”
