[2.1.8] Rocket filling unreliable

[Two]

Just tried the new rocket filling mode and had to learn that it is very unreliable. While it ordered partial amounts of most of the stuff needed for a minimal science platform, it also ordered 50 assembler (with just 3 needed) and 50 solar panels. Initially it loaded the 3 needed solar panels, then when I built another 3 it decided to order 50, even though other items were also in request. I have not found any way to tell how it will behave and no way to reproduce the bug.

Suggestions: make this a switch on the station to order partially or in bulk, with a button to send partially filled rockets immediately.
I don't see any way to detect what the player actually wants, bulk or single, unless the player tells you. And partially filled rockets will always get stuck half-full eventually.
