How to make routing with change of get parameters?

Question

Yii

Now there are the following rules:

'/<entity:(suppliers|customers)>' => 'firms/index',
'/<entity:(suppliers|customers)>/<action>' => 'firms/<action>',

Can you please tell me how to make the routing to firms/index with the get parameter entity = 'customer' when switching to /customers ?

'/<entity:(customer)>s' => 'firms/index',
'/<entity:(suppliers)>' => 'firms/index',
'/<entity:(suppliers|customers)>/<action>' => 'firms/<action>',
