Zoho Desk - Sub-customers/Sub-sites

Hi all,

I need some help with configuring  our Ticket Information. We have a customer in the hospitality sector with many different locations. 
I'd like to add a field for the Account Name & a field for the Site Name or something similar. I can see I can add a Single Line, but would this allow us to search like we do for the Account Name?

Ideally I would like to search for either: MyCompany or MyCompanySubSite and find the appropriate tickets. 

Hopefully this makes sense!

Thanks

Mike
