We would like to put an image on the UX dashboard, which can be clicked on to navigate to a specific link. Is this possible to do?
Interesting. Not sure if that can be done.
As of now It will allow you to navigate to different dashboards within the App if you click on those Images.
could be interesting development, for sure good to post on Idea Exchange https://community.anaplan.com/t5/Idea-Exchange/idb-p/AnaplanIdeas
For now, you would need to post Hyperlink itself in Line Item. You can use MAKELINK formula to create display name like 'Click here' or 'SharePoint'. See here https://help.anaplan.com/a4139862-e485-45b0-a835-60fd2b32a220-MAKELINK
The closest solution I can offer is that you use image and text link formatted field card to direct you user to the required website.
Use MAKELINK so that you can customise the text visible to the user.
