Just rename a file before moving...

Hi, I need some help. I want just to create an action to move a file to a specified folder. However, before move I want to add a simple string before the filename - e.g. "Bill -". As an example: I drag a file named "MyText.txt" to this action and the final expected result would be a file named "Bill - MyText.txt" on my folder Temp.

Please, I need your help to create a Python or any kind of code to make this happen.

Thanks in advance.
