Append custom field value into a custom URL field

[Pauletta Bingaman]

Can anyone tell me how I can append (concatenate) the value from a custom field into the URL stored in a custom URL field?  For example, I am already storing my Salesforce Opportunity ID in my JIRA issue.  I'd like to create a custom URL field that stores "https://na78.salesforce.com/" and appends the value stored in the Opportunity ID stored in the current record to give my users a direct link to the opportunity associated with the JIRA issue.  Thank you for any suggestions!

I don't think this can be done natively within Jira.  But that said, I think that you could use a plugin to Jira to get closer to this.   For example the Jira Misc Custom Fields will allow you to create calculated custom field values based on the other fields values.    In turn I think you might be able to create a custom URL based on the values from 2 or more other custom fields on that issue.

I found a similar post from a few years ago. Please see  MISC Custom Fields: Calculated text field. It looks like @David _old account_ was able to point out that this can work, but you will likely need to make sure you are adding the <a href=...> tag to make this a proper hyperlink.
