# [Tex/LaTex] way to add a field to the title page in beamer?

beamertitles

I have to add a \supervisor field to the title page of my presentation. Is there a way to do that in beamer?

I tried adding the supervisor information to the \author field, but the content of the author field are also displayed on the footer of all the slides, and I wanted just my name to be there. If adding a field is not possible is there
a way to display custom text at the footer?

\author[Your Name]{Your Name\\{\small Supervised by: Your Supervisor's Name}}
for example. The optional argument of \author is the short author, which goes in the footer.
