Formatting Descriptions on Ticket Forms

Hello! I would like the ability to either

1. Add formatting to the "Description shown to end users" part on a ticket form
2. Add a hyperlink or PDF to a ticket form

We have various "Service Request Types" that we want users to select from when they submit a ticket, and we want a way to define those for clients. This will help them decide which service request type is most applicable for their particular request. 

Right now, if I have various individual lines in the description with their corresponding definitions, the system lumps everything together into one paragraph on the end-user side. It would be good to be able to separate the lines, make some of the text bold, etc.

The second idea would be to link a URL or PDF document to the form so people could review it for more information about the types. It could say something like, "Click here to view definitions of the Service Request Types".
