Hi @gmassart. I have an iLogic rule you can try, but I haven't tested it, because I don't have prompted entries in any of my title blocks. It may be a little hard to understand right away, so I added several comment lines in the code to help. This just attempts to handle one promoted entry at a time right now, but loops through each sheet, and each prompted entry found in the title block of each sheet.
Dim oDDoc As DrawingDocument = ThisDrawing.Document
'or
'Dim oDDoc As DrawingDocument = ThisApplication.ActiveDocument
For Each oSheet As Sheet In oDDoc.Sheets
Dim oTB As TitleBlock = oSheet.TitleBlock
'get TextBox for the PromptedText we want to change
Dim oSketch As DrawingSketch = oTB.Definition.Sketch
Dim oTBox As Inventor.TextBox
For Each oTBox In oSketch.TextBoxes
If oTBox.FormattedText.Contains("<Prompt>") Then
'it contains a placeholder for Prompted Entry/Text
'get Prompt text (placeholder text, not resulting value), so we know which one it is
'Split() tries to break the String into an Array of Strings, breaking at specified point
'need to get text between "<Prompt" and "</Prompt>"
'Item (1) of that resulting String should be the second half of the String (after that break)
Dim oPromptName As String = Split(oTBox.FormattedText, "<Prompt")(1)
'Item (0) here should be the first half of the new resulting String (before the break)
oPromptName = Split(oPromptName, "</Prompt>")(0)
'get its current value in the title block (result text currently being shown in title block)
Dim oCurVal As String = oTB.GetResultText(oTBox)
'prompt user to enter new value for it, while showing its current value as default response
Dim oNewVal As String = InputBox("Prompt Name = " & oPromptName, "Edit Prompted Entry", oCurVal)
'set that new value to the prompted entry in the title block
oTB.SetPromptResultText(oTBox, oNewVal)
End If
Next 'oTBox
Next 'oSheet
