Basically
I have 2 MSI files
MAIN.msi and Optional.MSI
Each of them is 50 mb file.
I found that cool option to install MSI after main installed with chained option.
But also i would like to add this Optional.MSI inside installation folder of MAIN.msi
Is there any option that chained somehow can refer to file inside resources ( Files and folders) added to main.msi ?

Basically when i add MAIN to files and folders and add to chained my installation is 150 mb so im sure that inside that MSI i have 2x OPTIONS.msi file is there any option to add only one OPTIONS.msi file and those one Options.msi file refer to chained and files and folders ?
Best regards
