When flagging a question as needing migration to academia, electronics, signal processing, chemistry, philosophy etc, I end up at Flagging>Closing>Off-Topic>Migration which offers me just two options for migration: math stack exchange, or meta physics stack exchange. I then have to go all the way back to flagging it again, choosing the "other" option, and then typing in the migration site.
Would it therefore be possible to replace the two migration options with a general box where people can type in the site they think the question needs to be migrated to?
