Add attachment to particular category [Smart Attachments]

[Rafał Nowakowski]

Hey,

I want my users to add attachments to particular category (not default) on transition screen, without selecting this cattegory.

By default screen shows "Category_1" as first, but on that transition scrren i need it to show  "Category_2" instead. I tried adding there another field containing script in its description but it ddidn't work. Script below:

<script>
jQuery("#attach-cat-select").val(1)
</script>

where val(0) = "Category_1" and val(1) = "Category_2".

When i execute this script manually via browser console (google chrome) it works.

Any idea how to fix my script or any other soultions without any script?
