Ability to display custom properties ?

[Nazar65]

It would be good to add some settings which will allow to pull custom properties from jira issue such as for example fix_version or any other.

So the properties can include any values from custom fields:

`:PROPERTIES:
:assignee: User
:filename: tickets
:type:     Task
:type-id:  3
:priority: Normal
:status:   Ready for Code Review
:created:  2024-07-30T15:56:55.485-0400
:updated:  2024-08-01T10:49:02.812-0400
:ID:       ID
:CUSTOM_ID: ID
:FIX_VERSION: Release-123456789 --- this is custom field added
`

For now i had to add few customization to be able to display custom fields, but it would be good to have some list where i can define additional custom fields.
