Arduino Mega + Ethernet shield + sensor shield?

Hello,

I am glad to become a part of your community. I am about to build my first Arduino setup which consists of Arduino Mega 2560 R3 board, Arduino Ethernet Shield R3 and a third party Mega Sensor Shield V1.3 board by Keyestudio.

My first question is: can I stack both shields on the Mega board? The Ethernet shield is shorter as a form factor and does not provide coverage for all I/O pins. Is there a kind of a header riser or something similar available?

Thanks a lot in advance!
