Remove value from multi pick list field when mass editing

Hello,

is there a way to mass-remove a value of a multi pick list when mass editing leads?

I have the following case. For each lead, we keep track of the fairs where we meet them.

So, i.e.

Lead 1

Fair (multi pick list field): Fair 1, Fair 2, Fair 3

Lead 2

Fair (multi pick list field): Fair 2, Fair 3, Fair 4

So the question is: can I remove a specific value (i.e. "Fair 3") from each lead by using mass update?

Thank you

Thank you
