Edit Duration for Multiple Tasks Simultaneously?

I’m trying to figure out the impact on the whole project of expediting several out-plant tasks. For example I have 4 different “PCB fabrication” tasks with 4 week standard lead times and 8 different “Cable assembly fabrication” tasks with 5 week lead times.

For a fee I can ask my outside vendors to shorten those lead times to 2 weeks and 3 weeks, respectively.

Is there a way to link the durations of multiple tasks so that I can toggle between “normal” and “expedited” by making 2 edits instead of 12 edits?
