Extending the extension

My 90 days tourist visa expires end of May. I have been informed by Southern immigration office in Kaohsiung that there is an automatic 60 added to this visa for which no action need be taken. However as a Canadian passport holder I have the option of applying for a 90 day extension with some supporting documents. The question is if I were to take advantage of the extra 60 days granted to all and at the end of that period to apply for the formal 90 days extension, would that be possible or am I taking advantage and can only do one or the other?
