Make one SIP extension part of two different conferences

Hello,

I am new to Asterisk and am wondering if the following is possible.

Is it possible for a SIP extension to be part of more than one conference simultaneously. For example let us assume that there are SIP extensions 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019 & 2020. Could we have the following conference calls simultaneously.

a. Conference call 1 with extensions 2010, 2011, 2012, 2013
b. Conference call 2 with extensions 2012, 2013, 2014, 2015, 2016
c. Conference call 3 with extensions 2010, 2013, 2015, 2017
d. Conference call 4 with extensions 2014, 2015, 2018, 2019
