It would very interesting if we could select (pick) several corridor regions to set the same corridor Region frequency.
Right now, we can do it for BaseLine (all regions of that BaseLine with the same frequency) or for corridor (all regions with the same frequency), but we cannot select several regions of the same BaseLine (or another BL) to put the same frequency.
In my opinion, this would be solved if "corridor Region frequency" was a Style and each Region had a frequency style so we could change that maybe from the properties palette..
We could save different Regions frequency in the template and apply a style directly to a Region.
