The hotbar has a limited number of slots. Some games offer multiple hotbars but I'm not fond of this.

Instead you could allow scrolling through buildings to build with some hotkey (as the wheel is already for rotating). Could be limited to similar buildings, say you hotbar a conveyor mk1 and can scroll to mk2, splitter, lift, then back to regular conveyor ; or just scroll through all the unlocked buildings, in which case the hotbar would be like bookmarks in the building menu.

Middle Mouse Button could bring up a menu like when pressing C but for related buildable objects, using the same mechanics to select the lift mk2 for example
