How to update one word in the base project? I have to change "workstation" into "workgroup" in 100 strings

Hello

I have to change "workstation" into "workgroup" in 100 strings in Base project.

Please help me to find the feature how to update manually one word in source and target file.

Once I update Workstation into Workgroup insource file, then I have to update it manually in target (Polish language).

Thank you for support.
