Variables in custom fields

We use Lansweeper in our network

I would give my techs a direct link to Lansweeper dashboard.

The url should be like:

http://lansweeper/quicksearch.aspx?q=client@email.com

or

http://lansweeper/quicksearch.aspx?q=computername

The idea is to add a custom field like "http://lansweeper/quicksearch.aspx?q=[variable]" for client and assets.

Do you have any advice?

Thanks
