Yes, that's exactly how I do it, there are also tools in Bee to copy sources to WT.
I had a graphic illustration as to why a link by itself is inadequate, last week I went to update and improve a profile I created in earlier times on WT, before learning the importance of posting each source individually, and having only the FamilySearch link on the WT profile. I found someone had removed all siblings, and overwritten the FS person and ancestors to a different family from a different county.
