no, no, no... Nothing is impossible is this world...
To have this information...in the Installed tab... a script do something, make a task, do a job.
So, basically, save the result somewhere ln a buffer, a cache, a database, a files (in the unix way) and use this information the next time you have to use it.
To said the same thing with other words, in place to push the information " in real time", push the same information "for next time" and put the same information in "saved information"
And in place to use " the real time information" in the "installed tab".. You use the "saved information"
