Yes, but...
I couldn't find a way to do it using the EG point-and-click features. It's very easy to do in a code window. First, you have to turn off all of the result options in Tools -> Options -> the Results tab. Then submit code looking something like this:
ods _all_ close;
ods excel file="C:\Some Directory\SASTest.xlsx" style=EGDefault options(embedded_titles="no" embedded_footnotes="no" sheet_interval="proc");
proc print data=sashelp.class;
run;
proc means data=sashelp.cars;
class make;
var cylinders;
run;
proc tabulate data=sashelp.shoes;
class region;
var sales;
table region, sales*sum;
run;
ods _all_ close;
In your case, if you're comfortable, you can just grab the code generated in your 4 proc reports, and drop them into a program together.
Hopefully, someone a bit better with ODS will have a better suggestion.
