When in TechOne, under 'Workplaces' you can customise the main portal (and portlets) and render URLs. We've used this to do it successfully for our intranet homepage. However, when we tried to attach a Promapp minimode URL here, it said the TechOne browser was unsupported. We might be running an older version of TechOne, but it is theoretically possible with a newer version. Otherwise, our Support team may be able to work through it with you (email@example.com).
