Welcome to SW forums Steven
Seems like you're importing a step assembly file. The best way will be to use pack and go and use replace function to quickly rename them.
- Import the step file as you're already doing.
- While in imported assembly, click on File > Pack and Go
- In Pack and Go window, click on Select/Replace
- Now using replace option, change product-name to mystring
- Save your files and done.
The other way might be to use a macro that will import the files and at the save time save them with mystring in the file name.
