Merge Academy--Ongoing Issues In Main Grid

Now that the Stickerbook has begun as a new feature of the game,  the gifts that are awarded when part of the rooms are completed are regular matching items and occasionally a packet of stickers.  Once upon a time, the gifts also included the building blocks of generators that could be built up.  The building blocks were also available somewhat irregularly in the marketplace.  Currently, there seems to be no way to obtain those building blocks, and worse still, there is no way to get rid of the generator parts that are taking up space on the main game grid.  I have learned [the hard way] that the generators can be trashed in the alternate weekly grid, but the main game grid doesn't give you that option.

Basically, there need to be more ways to obtain the generator parts, or there should be a way to send the ones to trash that are taking up real estate on the main grid.  This is not a new problem, but I've only noticed since the stickerbook sideline was introduced.

Thank you for researching this please.
