You can create as many signatures as you want with AutoText. Click on "Help" from within Word, and then go from there. You'll get step-by-step directions. But, basically, you first type what you want to use as your signature. Then you block it, click on "Insert," then on "AutoText," then on "New." You give it a name. (As I recall, the very first one you create can use the Word-provided "Signature" as its name. Subsequent signatures need different names.) Do this for each signature you want to create.

Then, to use those signatures, you'd be in your document, then click on "Insert" then on "AutoText." You get a fly-out menu listing your different choices. There is a choice for "Signature," but your additional sigs may be listed under "Normal" which has its own fly-out menu.

Some of the directions vary according to which version of Word you are using.
