Compare Build Number to jfrog or bintray?

Does anyknow if its possible to configure a rule that can check your current build number to the latest builder number on either jfrog or bintray?

I would like to try and show a Text Item on a sitemap to potentially alert me to a build upgrade.

And then perhaps take even take it 1 step further with small bash script to apt-get update and upgrade OH2.

Also, Is it possible to show your current build number in sitemap?
