Control 32-bit register with buttons

Question

I am quite new with Labwindows.
I need to control a lot of 32-bit registers by using buttons to set or reset each bits.
(It would be so complicated to manage each button by  CALLBACK function).
Is there a simple way to controll array of buttons in Labwindows ? Or is there even a concept for "array of buttons" ?
Like in Labview with array and buttons as boolean variables.

If you are using CVI 2010 or later you can use arrays of controls which can help you in this issue: here a tip on using them
EDIT Wolfgang preceded me often! 
Going a little bit further on his idea of a single callback for several controls, you can add to the controls appropriate callbackData with which can taylor the behaviour of the callback. Suppose you install a single callback on 32 buttons and add the bit index as callbackData on each of then with SetCtrlAttribute (..., ..., ATTR_CALLBACK_DATA, (void *)index); with index from 1 to 32: when you enter the callback you can simply read the callbackData you receive to immediately have the index of the bit to manipulate. The callbackData can only be assigned programmatically, you cannot set it in the UIR editor.
Proud to use LW/CVI from 3.1 on.
