How to preserve the order of points in the selection field ?

I made a wrangle that should process the points in order of selection. But as I discovered, in the point selection field, the point numbers after selection are sorted in ascending order. I never thought about it before. This, of course, is visually convenient, but it’s the opposite of what I need. Is it possible to make sure that the point numbers are saved in the selection field in the order in which they were selected?

You could select your points in desired order then make a group node and reference the group nodes 'basegroup' parameter in your wrangle for your pt ordered(as picked) string values.

I feel there should be a more direct way to do this... it perhaps has something to do with soputils. I still haven't figured it out tho.

the Action Button in group parm for Attrib Wrangle would have to have:
kwargs['ordered'] = True
for it to preserve the selection order of points selected through that button, which it does not have

but if this is for the HDA wrapper then you can easily make that work for your HDA group action button

I thought VEX/VOPs can't have any interaction when processing in points mode? So I'm not sure how you would see a difference in your wrangle when processing points in a different order, other than in a printf.

The screenshot shows it's running in Detail mode
So I assume the group Parm is evaluated inside and fed into expandpointgroup() to later run over those points in order

But it's true there is no need to hijack wrangle's group Parm for this, you can make a new one and fix the Action Button to preserve the order as mentioned above
