Hi Mazze, many thanks for your reply and sorry to bother you during the weekend.
That is definitely answering my question about the slot name. For the sequence I wanted to link a shot to a sequence, for tracking purpose that is why I wanted to add a tag called <sequence> into the <shot> tag . but no biggie if it is not a feature, a basic regex on the <name> of the shot will do it!
I have one tiny last question that you could for sure help me with (a very stupid one!):
I've been looking in C:\ProgramData\Assimilator\Project\<Name_of_the_project> to find the entire project xml file, but only I can find the projectPaths.xml. I was wondering where was it stored by default? because I want to insert new shots within the project and not just as a playlist that is not attached to a project. Does it make sense?
Again thank you so much for your precious time and expertise with SCRATCH, this is a fantastic software!
