Would it be possible to have a variable time buff ?

One of the challenges with the game is balancing real life and gaming here. some valuable resource can not be run because the "buff end time" does not fall into the window for your gaming. If i could make a 10 hour buff or a 14 hour or 7 hour it would be ace.

No real need for these to have a "bonus" if done by someone else either (since they are precise times). You could slide a slider to vary the time from 1 hour to the max (maybe 24) and the cost changes. The just stamp the duration onto the icon so that you can see it easily in the star when it is time to use it.
