How to add multiple expirations of a futures contract to an instrument list?

[imphasing]

I want to have an instrument list with various expirations of the same futures contract, eg CL 1-17, CL 2-117, CL 3-17, etc.

In NT8 I don't see a way to add multiple expirations, what is the suggested way to do this? In NT7 I could just add each instrument with its own expiration individually, but in NT 8 I can only select the instrument itself, not set the expiration.

I think I could do this in a painful way, like add 1-17, edit the expiration to 2-17, add 1-17 again, change the expiration to 3-17, etc. Is this the only way I can do this?

Hello imphasing,
You may add in the expiry's by opening the data series and within the instrument select box please type in the instrument and the expiry. This way you may add in multiple expiry's for the same instrument quickly.
