Symfony form EntityType class

Question

I am preparing a form for the user's choice of a game according to selected parameters. I am using the EntityType class.

Example:

///...
-> add ('Age_of_years', EntityType :: class, [
    ' required '=> false,
    ' label '=>' Age from years: ',
    ' class' => Game :: class, 
    'choice_label' => 'Age_of_years ',
    ' expanded '=> true,
    ' multiple '=> false,])

Many games are assigned the same minimum age and when borrowing from the database, the same values ​​appear in the form many times. Surely there is a way to avoid it?
