VS 2008 Playing With The Designer - InitializeComponent - Forbidden Area ?

Alright so i have a form with alot (ALOT) of controls...many tabs, many listviews, many comboboxes and textboxes, all of which have values which i saveload using a class i made for saving and loading these values from a file.

Loading these values is pretty slow after the form loads. Takes around 3 seconds (i had to create a splashscreen and made it look decent, but it's still not a nice thing to have)

Then today i decided to try something. I opened the designer to initialize component, and i called the LoaderSub (that loads the values for the controls from a file) within initialize component, in a location after all the properties are set but before all the .resumelayout and .performlayout are called. Lo' and behold the form loaded in less than half a second, with the values and all.

However, now everytime i make a change to the form in design view, or even add a handler to some control in code view, the designer redraws and the auto generated code takes out my code from initializecomponent.

I did the googling, and all the results i found for similar cases issues were cases where the person asking the question im going to ask, the answer is "Didn't you read the part that says DO NOT MODIFY?"

Still, as a last attempt, I ask here: is there any way to modify initializecomponent without losing my changes? I just need to call LoaderSub before the layout resumes...if i call it before initialize component, i get null reference exceptions. And if i call it right after initialize component, loading is very slow.
