Is there a shortcut for accessing the current element?

I’m still not finding a way to accomplish this. @Support is this possible, or can we make it a feature request?

It’s defo possible but I think we’d need to see more of your code to understand what you’re trying to acheive and how.
When you say the button is dynamically built and therefore you cant get at the ID - what do you mean by that? are you not providing an ID and letting it auto generate one?
Why not just dynamically provide an ID to that element yourself? e.g give it a name but use a variable relating to a unique item in your table row - such as the ID or number of that record. so your button might be called “button_inqueue_$Number” (which translates to button_inqueue_37), then you can just reference it using that.

Thanks for the suggestion, I was able to get this to work; must not have been getting the syntax correct. Posting a snippet below in case anyone is looking for something similar in the future:

$transportDB = Invoke-SQLiteQuery -DataSource $dbFile -Query "Select * From  Vehicles ORDER By Number"

$Data = @(
    foreach ($row in $transportDB) {
        @{Number = $row.Number; Name = $row.Name; Zone = $row.Zone; Queue = $row.In_Queue; Pickup = $row.In_Motion_To_Pickup; AtLocation = $row.At_Pickup_Location; ToHub = $row.In_Motion_To_Hub; Gone = $row.CheckedOut}
    }
)

New-UDTable -Id "table1" -Data $Data -Columns $Columns -Sort -ShowRefresh

This gives me a table with UDAlerts, and I can act upon each alert in the different rows and columns as needed.
