How to translate {l s='Translate'} without mod parameter

[kandalf]

I bought a template that have some .tpl files with translations without the "mod" parameter, for example I have this in a .tpl file:

{l s='Please wait...'}

instead of 

{l s='Please wait...' mod='somemod'}

So the translation don't appear on backend, there are any way to translate this strings that don't have the "mod" parameter?

If it's a non-module TPL inside the theme, then you should be able to translate it by choosing "Front Office translations" and the theme name. If it's a module translation, you can't translate it without the mod='somemod', so you'll need to add that yourself and then choose "Installed module translations" and find the module and template name.
