Travel history query

Hello everyone,
I was filling out the tier 2 visa application and came across this question.
"Have you been issued any visa for the UK, UK Overseas Territories or Commonwealth in the last 10 years?"
I am an Indian citizen married to a trinidadian national and have been back and forth to trinidad since 2011 and I was given visa waivers (because of my Indian passport) with extensions every three months(they basically gave me time to arrange documents to apply for PR residence, but I never got around applying for it due to various reasons and eventually me and my husband moved to Oman)
Now I have visa waiver stamps and entry stamps for trinidad, do I need to add those dates for this question.
