email: is there any way to view / edit the SQLite database in Outlook for Mac to edit the signature file?

I'm looking to edit the file or the reference that is used in the SQLite database that Outlook uses on the Mac. Instead of having to copy and paste an HTML signature into the Outlook program, I would like to paste the HTML code into the base of data.
What programs or resources would you need to view and edit this part of the database that Outlook uses?

Database file

Library / Group Containers / UBF8T346G9.Office / Outlook / Outlook 15 Profiles / Main Profile / Data / Outlook.sqlite
