Inquiry from Potential new user

Hello,

First, this is a not a complaint piece, but I may word poorly, so wanted to say up front I am seeking information. I use today eWallet. I am trying to move to 1Password for what I see are a wealth of nice-to-have features.

But...
I started to manually move my entries over today and I immediately ran into a problem. Unless I am missing something (I sure hope I am), I am finding 1Passwords categories and templates too restrictive. I have data that does not fit into any of the categories and templates that 1Password provides.

I realize I could, in theory, use Secure Notes. But that is not going to work for me. I have hundreds of similar-type entries that share many fields types. Forcing structured data into a free-form field is not the right thing to do.

In eWallet I am allowed to modify a base generic template and rename fields and alter the type of data that they store so that I can create a new structured template. Can I not do that in 1Password?

I was dismayed to see three category/templates that were so specific in nature (Wireless router, Server, Database) but nothing more broad that I could use for other hardware types (stereos, cars, cell phones, computers, etc.). Surely people are not using Secure Notes to store such things, seeing as how these items have many common elements (serial numbers, warranty expiration dates, purchase dates, purchase locations, MAC addresses, model numbers, manufacturer names, model names, support phone numbers, and on and on).

In the end, my question boils down to: Is there a mechanism where I can create a custom template for structured data entry, or I am l limited to the categories (I assume 1-to-1 relationship between categories to templates) I see when I press the "+" symbol?

Thanks,
-Neil
