C4C Attachments in Central Repository

Dear experts

We have a requirement that attachments of any system (S/4, Ariba, C4C etc.) are supposed to be stored on a central repository. I am responsible for C4C and am wondering if this can even be achieved with C4C.

Would we actually be able to bring any kind of attachment (of account, contact, visit, task, survey etc.) into a DMS same as if files would be stored in C4C without risking many features in C4C incl. offline?

Has anybody done a similar thing before? Is this even remotely recommendable?

Thanks and Regards
Stefan
