Well, there is no simple workaround that I can think of short of implementing
the feature in MOST.
The complex part about adding the feature is becoming familiar with the
existing structure of most.m and toggle_dcline.m. Once you have a confident
grasp of the code in both of those, it should be relatively straightforward to
implement.
This would be a nice addition if you are able to implement it. And I suppose it
would make sense to move any further discussion to the MATPOWER-DEV-L list.
