Disable/enable filling an histogram

Hello Rooters

I'd like know if there a posibility to disable/enable filling an histogram for example :

we can imaging a such method TH1:Enable(Bool_t boolenable) with this behaviour:

TH1F <http://root.cern.ch/root/html////TH1F.html> *h1 = new TH1F <http://root.cern.ch/root/html////TH1F.html>("h1","h1",10,0,10);

h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(1); // fill bin 1
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(1); // fill bin 1
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(2); // fill bin 2
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(2); // fill bin 2     

h1->Enable(kFALSE);

h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(1); // no action !
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(1); // no action !
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(2); // no action !
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(2); // no action !   

h1->Enable(kTRUE);

h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(1); // fill bin 1
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(1); // fill bin 1
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(2); // fill bin 2
h1->Fill <http://root.cern.ch/root/html///TH1.html#TH1:Fill>(2); // fill bin 2

Thanks a lot for your help

Luc
