Add Transitions In to Out like Avid
After you Mark In & Out you use the command "Add Transitions In to Out". You get the options: duration (its not necessary to go to preferences), start, end, centre or custom position of your transitions. Extra Checkbox "don't change exitsting transitions". With a folder of transition templates (in Avid "Quick Transitions") you could see all your templates & select the right one for "Add Transitions In to Out"
