Reviewing through your description, this will depend on the specific version of Jive your instance is running.
If you are on a Jive Cloud instance I would recommend submitting a case in your customer group so that a member of our support team can assist with investigating the current options available for your instance.
If you host your own instance of Jive (Jive 8 for example) you should be able to modify the skin.default.landingpage system property in your instance to change the default landing page, for example
skin.default.landingpage = /your-view
Thanks very much Jesse! We own our own Jive cloud instance. I'll open a support case to check though.
