Declare VBScript inside of VBScript (Running multiple .VBS at a time) - vbscript

Question

I need to run multiple .vbs at a time. This is the only way I was able to find online:
Dim objShell
Set objShell = Wscript.CreateObject("WScript.Shell")
objShell.Run "1.vbs"
objShell.Run "2.vbs"
objShell.Run "3.vbs"
Set objShell = Nothing
To do that I'd have create 1.vbs, 2.vbs and 3.vbs separately. Is there a way to input them all as part of one .vbs file? Something like
Dim objShell
Set objShell = Wscript.CreateObject("WScript.Shell")
Dim vbs1 as vbscript
Dim vbs2 as vbscript
Dim vbs3 as vbscript
Set vbs1 =
"Set objExcel = CreateObject("Excel.Application")
objExcel.Application.Run "'C:\Users\test1.xlsm'!Module1.refresh"
objExcel.DisplayAlerts = False
objExcel.Application.Quit
Set objExcel = Nothing"
Set vbs2 = ' whatever code
Set vbs3 = ' whatever code
objShell.Run vbs1
objShell.Run vbs2
objShell.Run vbs3
Set objShell = Nothing
The purpose of this:
I have ~50 excel reports with connections to SQL that need to be updated every day.
To do that I've created a macro and added it to each of them. The macro refreshes connections/queries > refreshes pivot tables > removes the connections/queries > saves as a macro-free workbook in a specified location.
I wrote .vbs scripts for each report. It just runs that macro in every Excel workbook.
Instead of running every .vbs separately, I've created one main .vbs that references all prior created .vbs to run them at the same time.
My question is if there's a way to do that without creating 50 separate .vbs files.
