Hi @Anonymous
There's a VBA code posted about this by @Anonymous here:
https://forums.autodesk.com/t5/inventor-ideas/drawings-re-number-detail-amp-section-views/idi-p/6276556
As an iLogic rule it'd look something like this 
Sub Main
Dim oDoc As DrawingDocument
Dim oSheet As Sheet
Dim oView As DrawingView
Dim iter As Long
'check if active document is a drawing
If ThisApplication.ActiveDocument.DocumentType <> kDrawingDocumentObject Then
Exit Sub
End If
oDoc = ThisApplication.ActiveDocument
iter = 1
'Rename detail and section view identifiers on all sheets
For Each oSheet In oDoc.Sheets
For Each oView In oSheet.DrawingViews
If oView.ViewType = kDetailDrawingViewType Or oView.ViewType = kSectionDrawingViewType Then
oView.Name = num2Letter(iter)
iter = iter + 1
If InStr(1, num2Letter(iter), "I") > 0 Or InStr(1, num2Letter(iter), "O") > 0 Or InStr(1, num2Letter(iter), "Q") > 0 Then
iter = iter + 1
End If
End If
Next oView
Next oSheet
End Sub
Public Function num2Letter(num As Long) As String
'converts long to corresponding alpha
'Ex. 1 = A, 28 = AB
remain = num Mod 26
whole = Fix(num / 26)
If num < 27 Then
If remain = 0 Then
num2Letter = "Z"
Else
num2Letter = Chr(remain + 64)
End If
Else
If remain = 0 Then
num2Letter = Chr(whole + 63) & "Z"
Else
num2Letter = Chr(whole + 64) & Chr(remain + 64)
End If
End If
End Function
