Notice - if you have custom theme and modified review form template file Magento_Review/templates/form.phtml you have to add manually order_id input (see example in file view/frontend/templates/review/form.phtml):

<div class="field review-field-order-id required">
    <label for="order_id_field" class="label"><span><?= $block->escapeHtml(__('Order number')) ?></span></label>

    </div>
</div>

Prices import

If you have custom script to import prices, you can use method \Macopedia\OmnibusDirective\Model\Product\HistoricalPrice::getHistoricalPriceUpdateValue to calculate historical price. As parameters, you should pass array with original prices $origData (before import values):

$origData = 
[
    'special_price' => xxx,
    'historical_price' => xxx,
    'price' => xxx
]

and updated prices array $data (after import values):

$data = 
[
    'special_price' => xxx,
    'price' => xxx
]
