Dear Dojo,

What is the best way to use a placeholder that refers to the DMA i am connected to in a URL?
I am asking specifically for a button that should open the Cube desktop application on a certain service card.  This should be possible by configuring an action (Navigate to a URL) on the button using the following URL:

cube://<IP Address>?service={FEED.Bookings."Timeline 3"."Selected items"."Query rows"."Service ID"}

I would like to replace the fixed IP address <IP Address> with a placeholder that resolves to the DMA that I am connected to so that the Cube session also uses that DMA.  How can this be done?  <DMAIP> as is possible to link to a web page in Visio doesn't work.

Thanks!
