Please paraphrase this text
Where there is scope for reallocating appropriations under the heading requiring additional expenditure, the Commission shall take this into account when making the necessary proposal, in accordance with the Financial Regulation, by means of the appropriate budgetary instrument.
When submitting the needed proposal, the Commission will take into account the possibility of redeploying funds within the heading where further expenditure is needed and will propose the application of an adequate budget instrument, in accordance with the Financial Regulation.
