Adding arguments to URL string for new ticket form

Right now, if I type in a URL like this:

https://mydomain.teamdynamix.com/TDClient/30/Portal/Requests/TicketRequests/NewForm?ID=czv4Fxr7fgI_&RequestorType=Service

It takes me to a new ticket form for a specific Service, which is pretty handy.  What I'm wondering, is there just a way to append additional arguments to the URL string?  For example, something like: “&SourceURL=https://mydomain.sharepoint.com/sites/somesite/Lists/ListThatIsHavingIssues” where that “SourceURL” that would go into a field on the new Request Form?  It doesn’t have to pull that URL automatically, that could be “hard-coded” into the URL string for my purposes.
