highlight a set of nodes with given IDs or coordinates; similar as 'interactive select points on'

‘Interactive select points on’ allows to query information of the data defined on nodes of the grid and draws a kind of bullet point on the selected nodes.

Say I know the ID or the coordinates of the nodes of interest, is there a way to imitate the ‘interactive select points on’ filter?
To be more precise, I would like to have similar bullet points (or any other shape to distinguish them from the remaining nodes) on these nodes, without having to click on all nodes individually but rather reading the IDs from a file, or punching them in a window,…

Thank you!

Hi, Simonw

have you managed to solved your problem? If so, would you care to share your approach? I want to perform this very same task.

Thanks a bunch!

I am afraid, but I have not put more thoughts on this.
