default setup time by space
There is a system wide setting Begin Setup buffer that makes you leave a certain amount of time between one event and the next.
I propose that this setting can be overridden by a required setup time setting set on the individual spaces.
The setting in the General settings would be used unless, the space had a specific different amount of time listed.
THEN it would go with the time for the space that has the longest setup time selected.
This is needed because for many of our rooms we need very little turn around time as very little setup has to be done. For most rooms we need 2 hours however. And for a few larger rooms, we like to leave 4 hours between events.
