enable shift+Click to add item to planner filters in blueprint library

[tldrlol]

this actually works in some cases. i'm not sure between bug/oversight/missing feature.

what works:

place empty deconstruction blueprint in character inventory.
right click it to configure.
shift click any other buildable from your inventory.
said buildable is added to the filter list of the planner.

what doesn't work:

place empty deconstruction blueprint in blueprint library.
right click it to configure.
shift click any other buildable from inventory/ghost cursor selection.
nothing happens.

as you may imagine, this discrepancy is more annoying with space age's reliance on map mode.
