Dashboard Updates for Significant Individual Filing

LAUNCH FILING and VIEW FILING RECORDS
AS the owner of a company, or representative of a company
I want the ability to view a summary of my significant individuals, launch a significant individual filing and view a ledger of past filings
SO that I can ensure the Business Transparency Register matches my internal transparency register.

REDIRECT TO SIGNIFICANT INDIVIDUAL FILING
AS a business owner or representative of a business owner
I want a reminder in my to-do list to complete my Transparency Register after Incorporation
SO that I am reminded of my requirement to file a Transparency Register
AND can easily access the required filing

DO NOT DISPLAY FOR PUBLIC COMPANY
AS the Ministry of Finance
I want to ensure that Registrar's Transparency Filings / To Do list items for those filings do not show for public companies
SO that BC Registries is compliant with legislation
