Disabling cell updates

I wasn't sure if I should ask this question on the api
list, but here goes.

One Solver user has requested that I disable refreshing of
cells while
it's converting a model from the sheet to the standard
format (by
setting the value of a cell to 1 and those of the others to
0, and
repeat for every single cell).  This cell update action
obviously
consumes significant CPU cycles so much so that scrolling
the sheet to
hide the data area prior to slick "Solve" speeds
up the execution.

My question is, is it possible to disable repainting of
cells while
their data are being modified?  Something like:

disableCellUpdates();

<convert models>

enableCellUpdates();

would be the most desirable, but I'm not sure if such API
exists.

Thanks in advance,
Kohei

You can use lockControllers / unlockControllers from the
document's 
XModel interface.

It amazingly works well.  Thanks a lot!
