  The Belle-II experiment is expected to collect large data samples at the
$\Upsilon(4S)$ and $\Upsilon(5S)$ resonances to study primarily $B$ and $B_s$
mesons. We discuss what other data above the $B\bar{B}$ threshold are of
interest. We propose to perform a high-statistics energy scan from the
$B\bar{B}$ threshold up to the highest possible energy, and to collect data at
the $\Upsilon(6S)$ and at higher mass states if they are found in the scan. We
emphasize the interest in increasing the maximal energy from 11.24\,GeV to 11.5
- 12\,GeV in the future. These data are needed for investigation of bottomonium
and bottomonium-like states.
