Auto update Summary on create issue screen or show bold text under Summary field

[vcatl2020]

I reviewed quite a few posts and looks like this is NOT possible without add-ons but still wanted to check.

Summary is a required field in JIRA cloud platform and I do NOT see a way to make it optional on JIRA software project field configuration. To workaround this problem, I could neither find a way to set a default value in Summary field on the create issue screen nor add a bold text (injecting javascript code into the description box of Summary field).  We do not want to go for add-ons just for this purpose, so wanted to run by community for seeking expert solutions.

Since you are on JIRA OnDemand the answer is No. Is there a reason why you don't use a version picker where the complete versions are stored?

Thanks for the info Udo. The example was just that. I actually want to join several casscading boxes into one field value that I can use in another db lookup.

thx
