Is there a way to edit the multiple extension under Provision-> date format?

[Song]

Hi,

I have 40 yealink phone T46s. Is there a way to tag them all and edit the provision? i need to change the date format and also the light blinking to only voicemail.
I can do it one by one but its time consuming.

I tried to tag them all and hit edit, but that function do not show up under the provisioning
