Joining two after effects projects

I am only new to after effects so please forgive my ignorance! Can anyone tell me if you can join multiple after effects projects that have been purchased so they become one project ?

You can import projects like you can import footage and stills.

Make new file.

File -> Import (select AE project 1)

File -> Import (select AE project 2)

-f.

Thankyou very much for taking the time to explain that to me, your help was very much appreciated! Now I can move forward! Take care, Nicole
