Applying a profile to an existing sequence (preserves target data and events) is very similar to creating a new sequence from a profile...

Description: Using an existing sequence (one with defined targets, events and frames), select "Apply Profile to Sequence" from the "File" menu.

This will bring up the Equipment Profile Chooser Menu:

Select the profile you would like to use and click OK.  

Doing so will alter the equipment profile attributes of a sequence, but will not alter targets, events or frames.  Keep in mind that the application of a new profile to an existing sequence could create some issues with filter settings.  Because sequence events are not altered during this process, it is possible that it could be trying to use a filter that simply does not exist in the new profile.  If this happens, SGPro will display a warning that you need to fix this event before running the sequence.
