Joining an RNAV Final Approach Course

[I9311I]

Is there a way to join the RNAV final approach course if you're vectored off? In the 737, arming approach mode does this, so I assumed this worked the same way...

Go DCT with intercept, the intercept course (inbound!) can be selected on the bottom right corner of the DCT FMS page.

I’m sorry, can you break it down a bit more, please?

I am sorry but I am not quite certain how I should do that. I currently do not have access to my copy so I can‘t send you screenshots but as I said, the option is on the bottom right corner of the Direct page on the FMS, which if my memory serves me correctly, is right above the FMS IDX button. There you should have an inbound course that you can change

I guess my question is Direct to what?

Direct to any point on the final approach course, then input the inbound approach course as the course intercept in the bottom right LSK 6R. The other way to do it is to take any point on the final approach course and put it in the top left LSK (1L) to activate the leg.
