support for combining or concatenating fields

I wanted to add my name to the feature request discussed at this old topic with @Ben : https://1password.community/discussion/74155/concatenate-password-with-onetime-password/p3

It would be great if we could create entries (maybe in a text field?) that are concatenations or combinations of other entries. For example, a field with a syntax like {password},{otp} would be perfect for signing into our VPN.

For those of you in the same boat as me, I also wanted to give an update to the script that @pcfleischer provided back in that post. The CLI has changed so his snipped doesn't work. Here's what works for me now:

vpn-clip() {
  # get the password
  item_password=$(op item get your-1password-item --fields label=password)
  # get the one-time code
  item_totp=$(op item get your-1password-item --otp)
  # concatenate and put them in the clipboard for pasting
  echo -n $(echo "${item_password},${item_totp}") | pbcopy
}
