Ability to combine upgrades?

[LagBolt]

Lets say you have a building at lvl 1 and want to upgrade it. Should it be possible upgrade from lvl 1 to any other lvl directly?

eg.
if lvl 1 to 2 cost 10,000 and 4h
and lvl 2 to 3 cost 20,000 and 8h

Could you have just 1 upgrade that went from lvl 1 to 3, costing 30,000 and 12h

I get annoyed when an upgrade finishes in the night and I have to wait to the morning to start again. Why not just combine them both

Thoughts? Could this be implemented?

Just pick your upgrades so they won't finish in the night.

just choose something else to upgrade so upgrade would finish during day. I sometimes add some simple short term defence buildings upgrades in the middle to time upgrades correctly ;)
