Mastering with analog gear and plugins simultaneously

2017 MacBook Pro, OS is High Sierra, Studio One 3 Pro

I want to master my tracks in Studio One 3 and use plugins and analog gear simultaneously.

Am wondering if the Quantam will be able to perform this task.

Can I take the Quantam outputs 3 and 4 coect them to inputs of an analog EQ and take the outputs of the analog EQ and bring them back into inputs 5 and 6 (or any of my choosing) of the Quantam and be able to process/master my tracks along with plugins?
