short pin codes

I love 1password for its friendly user interface. However I have one problem. I often store pin codes or a code of a lock. I do not want this field to be directly visible so I store it as a password so it is protected by **** . And the nice thing about the password field is that you can show it in large font (this is very use fulle). When I do dit I get notifications that my password is too short for all my pin code fields. This is not very friendly because I would like too keep track on insecure passwords and no I have to figure out which one are pincodes and which one are not. 

What I would like is a simple option to add a pincode instead of a password and that there is a new pincode field which works just like the password field but is not used in the watch tower. The only work around I found so far is to add a social security number and then to change the icon into something which makes more sense. Sometimes you also need a password field which can also be done using the social security number. 

Would it not be better not to use work arounds? It would be much better if there was:

• An option to add a pincode  or short code (with a nice lock icon)
• An pincode field which can be added to any item. (which functions like a password but is not checked by watch tower, so no weak or terrible behind it)
