Company Issued Options

Currently to find a company issued option (eg OXROA) I do a search on Traded Securities for the underlying security (eg OXR), then and then check our that which gets returned,

Sometimes however the results returned can be quite huge and there is the risk of missing some.

I was wondering if there is a better, more filtered/accurate way of finding what company issued options are available and their details.
At the moment I rely on the "header" of the security as to its expiry ... but how do you find things like Exercise Price etc?



Cheers
