How to globally update and amend opening reception list?

Hi,

Can you globally amend/update an attribute linked to multiple constituent records?  We are looking to amend our opening reception list attribute to say No instead of Yes? But is there a way to do this which doesn't require going into each individual record and selected No as the option from the drop down. 

This is a separate from globally updating/amending a plan. 

Many Thanks

Joanna
