  Virial-like identities obtained through Derrick's scaling argument are
powerful, multi-purpose tools to study general relativistic models.
Applications comprise establishing no-go/hair theorems and numerical accuracy
tests. In the presence of a horizon (\textit{aka} boundary), the spacetime can
be divided into regions, each with its own identity. So far, such identities
have only been computed in the region outside the event horizon; however,
adding a positive cosmological constant endows an additional boundary (the
cosmological horizon), with the region between the latter and the former of
particular interest. In this letter, by performing a radial coordinate
transformation, we generalise Derrick's scaling argument to compute virial
identities \textit{across the whole} non-asymptotically flat spacetimes. The
developed method is applied to the entire Reissner-Nordstrom-de Sitter
spacetime. A convenient gauge that trivialises the gravitational contribution
to the identity between horizons is also found.
