Measure with condition based on date slicer

I managed to do what I wanted, here the final measure for those who might be interested:

ca_reel_agent_v2 = 
VAR grouped_by_filter_date = 
SUMMARIZE(
    FILTER(fact_valo_imputation,
        fact_valo_imputation[date_imputation] >= [min_slicer_date] && fact_valo_imputation[date_imputation] <= [max_slicer_date]
    ),
    fact_valo_imputation[task_id],
    fact_valo_imputation[agent],
    "min_imputation", CALCULATE(MIN(fact_valo_imputation[date_imputation]), ALLEXCEPT(fact_valo_imputation, fact_valo_imputation[task_id], fact_valo_imputation[agent])),
	"max_imputation", CALCULATE(MAX(fact_valo_imputation[date_imputation]), ALLEXCEPT(fact_valo_imputation, fact_valo_imputation[task_id], fact_valo_imputation[agent])),
    "exceeding", CALCULATE(FIRSTDATE(fact_valo_imputation[exceeding_date]), ALLEXCEPT(fact_valo_imputation, fact_valo_imputation[task_id]))
)
return CALCULATE(
    IF(
        COUNTAX(FILTER(grouped_by_filter_date, [exceeding] >= [min_slicer_date] && [exceeding] <= [max_slicer_date]), [exceeding]) > 0,
        SUMX(
            SUMMARIZE(
                grouped_by_filter_date,
                "sum_valo_imput", CALCULATE(SUM(fact_valo_imputation[value_after_exceeding]))),
            [sum_valo_imput]
        ),
        SUMX(
            SUMMARIZE(
                grouped_by_filter_date,
                "sum_valo_imput", CALCULATE(SUM(fact_valo_imputation[value_before_exceeding]))), 
            [sum_valo_imput]
        )
    )
)
