Importing Layers from Project file

Hi All,

I'm looking to create a master After effects file with all the templates I normally use on a daily basis and then tie it into a script UI panel so I can call individual comps and place them into my new comps without importing the entire project and clogging up my workflow.

Any ideas?

I currently am doing a lot of if then statements to build specific solids and effects layers but the templates change so much that I think hard coding them is the wrong way to go.

Any help would be great.

Thanks.

Ben
