Stop the backup of external library components

Hello everyone,
I work on WF5 and SmartAssembly 5.0.

I have an assembly main who contains assembly and components and the assembly main contains flexibles components stored in an external librairy.
I would like to rename all the components, assembly and drawings contents in my repertory.
I use the function:
SET_MDL_NAME
This function works but it create multiple new versions of my flexibles components stored in my external library when the function save.
Do you know a command to stop the backup of external library components.

And do you know a function to find the name of drawings in the working directory as:

GET_MDL_NAME

Thanks
