HTC One M8 :: Support For Call Transfer Option?

I am thinking of getting a HTC One M8 phone, but first need to check that it supports Call Transfer as I need this option for work purposes. Here's the scenario:

- I get a call through from our business number which redirects to me
- I talk to the caller and they say they're looking for Bob
- I say I'll see if Bob is available and will transfer you over to him
- I follow the steps in the "Setting up a conference call" section of the documentation to put the caller on hold, call Bob and add him to the conference
- However I now want to drop off the call and let the original caller and Bob continue.

On the Samsung Galaxy S4/5 and Note 2/3/4 there is an option at this point to "Transfer Call", but I don't know if that option exists on the HTC One M8. The link says that I can tap a button "... to access options such as ending the call with a participant"
