Upgrading industry by specific value

[PetrOs]

After a few years, I came back to WitP. I could remember all stuff, but one thing eludes me. Was there a way to expand a facility by a specific value, not just doubling its production? For example, I have an aircraft factory of size 24, and I want it to be exactly 30... How do I do it? Just plainly clicking (or click with ctrl, shift or alt, right or left click) causes it to double, which is undesired.

If you do it through the Industry Management screen (the Factory icon on the top bar), you can choose to expand in increments of 1, 10 or double.

And max 100 points of that industry increase at that base on that turn. So if your industry had 150 points already, you can only double to 100.

Thanks! It works, I knew it was hidden somewhere!
