Hi, is there a way to edit the geometry selection of a Blast node?

I've selected some primitives in the viewport and then deleted with a Blast, but how can I edit the selection after the blast is applied?

I've heard there is a way to do this with the “backitck” key, but I don't have it on my keyboard: is there any other solution?

Use arrow button at right of group parameter.

Thank you it works!

Select the Blast you want to modify, press the white arrow on the right of group parameter, select the primitives you want to add in the viewport and hit enter
