Save relative path for raster files

Hello

I have an issue with none microstation user colleagues moving photos & pdfs i have attached to a microstaiton drawings or moving the project file completely, which then drops the links to the raster files attached. Is there a way i can make Microstation automatically save relative path to raster files?. 

The photos i attach are from different folders each time so setting it to one folder is not what im looking for. I just want it to auto save relative path.

I looked through loads of existing questions on this but i could not seem to find a relative answer. Im using Descartes stand alone   V8I Series 5 

Thanks
