Have makefile to have new pairs of source file indicated by its extension name

abdu

How can I modify a makefile to have few new pairs of source file indicated by its extension name to be compiled by Make automatically correctly and preferably interactively
#...

objects = a.o  b.o c.o d.o e.o f.o main.o h.o i.o
 
Binary : $(objects)
     g++ -o Binary $(objects)
#...
#...

now its source should be added
e.aaa.cpp and i.aaa.cpp ,
e.bbb.cpp and i.bbb.cpp ,
e.ccc.cpp and i.ccc.cpp

how can we have Make now to produce 4 binaries from those module with addition of 3 pairs of source files above while all the rest held still constant
