The only way to do that with the base system is to tie a form to the Help Topic field. It will automagically add the form associated with the help topic (on new tickets) when it is selected.
There is also a paid third party plugin that does something similar to what you are describing. It is called SuperLists and is mentioned here on me Resources for osTicket list on my site:
https://tmib.net/resources-for-osticket/
I also mirror this list here on the forums:
https://forum.osticket.com/d/92286-resources-for-osticket
I have never used this plugin nor has it been evaluated by osTicket for usability. Translation: if you want to use this 3rd party plugin you do so at your own risk.
