Loop on control flow so file loads in excel seperatly

Hi

I have one pre existing package which has source which exec a sp with parameters and dump that into excel file at a location now it is something like this,

exec [dbo].[sp_name]
 @planlist = '1,5,20'

so this is what we have in a source, and working great now the problem is we got some more plan ids like 4,27,28 and i have to built in one package only so it should be like loop like,

[dbo].[BHS_UP_PROVIDER_METRICS_PLAN_NETWORK]
 @planlist = '1,5,20' ---- takes this and load in one excel with given name

goes for a loop and 

[dbo].[BHS_UP_PROVIDER_METRICS_PLAN_NETWORK]
 @planlist = '4' ---- takes this and load in one excel with given name

then 

[dbo].[BHS_UP_PROVIDER_METRICS_PLAN_NETWORK]
 @planlist = '27' ---- takes this and load in one excel with given name

then 

[dbo].[BHS_UP_PROVIDER_METRICS_PLAN_NETWORK]
 @planlist = '28' ---- takes this and load in one excel with given name

and so on

now as you see planid could be single value or multiple...how to take care of this in a single package?
