No. Publisher is only in the Title table. It is not in the Issue table.
Which is why it has to be referenced as ComicTitles.Publisher in an Advanced Find instead of just using an I (which indicates Issue) for I.IssueNumber
If you do decide to upgraded to Pro (I think that has advanced find) or Archive and what to know some of the basic Advanced Find 'stuff', look at the Advanced Find Guide 'someone' put together
